IMPROVEMENT IN TILE ROOFING. I

Specification forming part of Letters Patent No. 36,225, dated August 19, 1862.

To all whom t may concern,.-

Beit knownthatwe, IsAAcMARsH, Jr., of the borough of Milton, county of Northumberland, State of Pennsylvania, and GRIGGs MARSH, of the borough of Lewisburg, county of Union, State of Pennsylvania,- have invented an lmproved Tile Roof, with the following advantages over other roofs commonly in use: first, it is perfectly fire-proof; second,from the manner of its construction it can be used as a perfectly flat roof, or equally as Well for a comb or steep roof; also, that it makes a smooth-surfaced roof, and in its cheapness, which will not exceed the priceof a first-class shingle roof, and from the manner of constructing the joints together it is impervious to either snow, air, or water, combining advantages over shingle, slate, tin, or composition roofs now in use when considering its cheapness,durability, and fire-proof qualities; and we do hereby de clare that the following is a full and exact description thereof.

The nature of our invention consists in using flat burnt earthenware tile, either square or oblong, of different sizes and thickness, and in laying them so as to make a fiat-surfaced vroof or smooth-surfaced comb-roof, and in making water-tight joints by using strips of tin, zinc, or other metal covered with mnslin or other soft material, inserting the saine with cement in the grooved edges of the tile-plate.

To enable others skilled in the art to make and use our invention, we will proceed to describe its construction, having reference to the draft accompanying this specification.

A in draft being tile-plate, B parts of tileplate to finish with.

O shows the joints between plates filled with cement, and also on the grooved edges, where the tile isjoined together by the use of tin or other strips embedded in cement.

D shows at the two corners a portion each of the tin plates or strips half embedded in the stationary tile ready to receive the cement and joining together of another tile.

E shows the grooved edges of the tile-plates. The tile being made of burnt clay or other yearths of a fiat surface and of any required size, shape, or thickness, and in having the edges grooved of a sufficient width and depth to admit of a piece of tin or zinc or other metal wrapped in muslin or other soft or pliable material, said piece or strip, after being (lipped or embedded in cement, to be placed in the groove of the tile-plate with sufficient cement on the edges and in the grooves to make a tight joint, said cement being made or composed of coal-tar with hydraulic cement or clay or other earths, the strips of tin or filling being so arranged as to break or coverjoints, so that in nailing or screwing down the plates to the root the pliability of the tin or other filling, with the tension of the cement, will make the tiles acccommodate themselves to the settling or straining ofa roof or building.

The thin metal connecting strip so constructed is strong and elastic andrequires but a narrow groove to receive it, thereby saving the strength of the edge of the tile-plate, said strips of metal to be left out, if chosen, in the construction of a cheaper roof, which will be made of the same kind of tile, only the edges left plain and lnot grooved'and cemented together as plain work, and .in laying this kind` of roof in cement or in mortary on a board flooring. Y

What we claim as new, and desire to secure by Letters Patent, is-

The grooved tiles and thin strips of metal or other elastic material, made and joined together so as to construct a waterproof and lire-proof roof, in the manner and for the purpose herein fully set forth.
